Spectrum Analysis of Optical Pulses by Difractional Spectral Devices

Within the framework of the radio-optical approach and on the basis of methods of optical processing of information, analyzing systems of diffractive optical spectral devices - lattice and prismatic, including a dispersing element (diffraction grating and prism), two layers of free space and a positive lens between them are considered. At the output of the analyzing system, complex instantaneous spectra are formed, which made it possible to perform computer simulation of the interaction of a difraction spectral device and an optical pulse.
